Gallup’s tracking poll, based on a three-day rolling average ending Sunday, put Trump’s average approval rating at 33 percent, the lowest of his presidency, with 62 percent disapproving of the job he’s doing — a new high.

Both polls were conducted before Trump’s former campaign chairman Paul Manafort and Manafort’s former business associate Rick Gates were hit with charges in the investigation by special counsel Robert Mueller into Russian interference in the U.S. presidential election.

Still, news reports that the indictments against someone were coming leaked over the weekend, which may have had an impact on the Gallup numbers.

Gallup reported earlier this month that Trump’s average approval ratings for the third quarter of the year stood at 36.9 percent, down from his second quarter ratings of 38.8 percent.

The Gallup poll is conducted among 1,500 adults and has a margin of error of plus or minus 3 percentage points.

Trump has consistently fared worse this year in Gallup’s polling than in many other surveys, but several recent surveys have showed him dipping back below 40 percent approval after a modest September uptick.

HuffPost Pollster’s aggregate of public polling gives Trump an average 38 percent approval rating as of Monday evening, with about 58 percent disapproving.
